摘要

The Leung' s Gauze of the present invention comprising essentially of astainless steel gauzecoated with the following mentioned photocatalytic solution. Thephotocatalytic solutions of thepresent invention comprise essentially of about 0-10 weight % of Nano-GradeMetal Oxides,about 0-1 weight % of Thickening Agent, about 0-3 weight % of QuaternaryAmmoniumBromide, about 0-5 weight % of Organic Acid (1), about 0-5 weight % of OrganicAcid (2),about 0-8 weight % of Alkylene Glycol, and about 80-95 Weight % of DistilledWater.The whole set up can effectively eliminate the VOCs, including Formaldehyde,through thedestruction or transformation of VOCs to innocuous end-products, i.e. CO2 andH2O.
